(De Man, 1916)
Diagnosis:
Carapace smooth between the ridges and large spines. Longitudinal spinulose cardiac ridge present. Chelae of first pereiopods weakly ridged and finely granular. No distinct spine present in middle of inner margin of merus of first pereiopod. Transverse grooves absent from abdominal tergites two to five.
Type:
Type locality: Near the Kai Islands, Indonesia, "5°40'S., 132°26'E., 310 m. Bottom fine, grey mud". Syntypes (5 males, 4 females) in ZMA, no. De 104.197, condition fair
Geographical Distribution:
Indo-West Pacific region: Indonesia (type locality only) and Australia (Coral Sea north east of Cape York, and north west of Melville Island, Western Australia).
Habitat and Biology:
Depth range from about 300 to 310 m; bottom: soft sediments, like fine grey mud. Ovigerous females found in December.
Size:
Total body length 11.5 to 18 cm; ovigerous females 13 and 13.5 cm.
Interest to Fisheries:
Potential. The size of the specimens, the fact that they are not solitary (the type haul contained 9 specimens) and that they live on trawlable bottoms, makes them of potential interest for commercial fisheries. But too little is known about the habits and actual habitat of the species.
